RECIPROCATING MOTOR.

1,129,264. Original application filed June 27, 1911,

Wheeling, in the county of Ohio and State of West Virginia, have invented a new and useful Reciprocating Motor, of which the following is a specification.

The present invention relates to improvements in reciprocating motors and more especially adapted for application to the enameling table set forth in the Patent No. 996,226 dated June 27, 1911, one object of the invention, being the provision of a novel form of motor for tilting the ware carrying support, by means of which any sudden jars at either end of the stroke of the piston of the motor is properly cushioned so that the mechanism for rotating, tilting and elevating the ware support is relieved of any damaging effect, during the operation of the table.

i A further object of the present invention, is the provision of a motor mechanism for tilting a ware support of an enameling table, in which the ends of the motor are provided with cushioning chambers, the-piston being provided with oppositely disposed reduced pistons for entering such chambers to coact with the fluid within the respective chambers to compress the same and thus produce a fluid cushion eflect at the full stroke of the piston, thus relieving any jar whatsoever upon the piston and reducing.

the wear of the same at the ends of the cylinder. i I

A still further object of the, invention, is the provision of a valved by-pass at each reduced end of the piston, by means of which at the initial stroke, the pressure fluid imparting the stroke will be admitted into the chamber at the rear of the base of the reduced end and thus assist in propelling the same in the desired direction, the valve being so mounted as to close the by-pass as the forward reduced end enters its chamber so that the pressure fluid will be properly compressed therein to cushion the stroke.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of Specification of Letters Patent.

Serial No. 996,226. Divided and this application filed August 7, 1913. SerialNo.783,643.

the invention herein disclosed can be made withmthe scope of what isclaimed without departing from the spirit of the invention.

in the drawings.Figure 1 is a fragmentary side elevation showing the motor for elevating the ware support and the present motor for tilting the same. Fig. 2 is a longitudinal sectional view through the motor for tilting the ware support, the said motor being broken away in the center to foreshorten thesame. Fig. 3 is a bottom plan view of the outer cap of the motor removed.

Referring to the drawings, the numeral 1' designates the base or pedestal of the enameling table, (not shown), which carries the motor 2 for properly elevating the ware support (not shown), there being connected to the motor 2, an actuating lever 3, whichis operably connected to the cross head 1 which travels between the members of the guide 5, which is properly supported upon the pedestal l and is connected to and supports the motor 7 for imparting the desired tilting motion to the actuating lever, as particularly set forth in the before mentioned patent.

The tilting motor 7, as particularly shown in Fig. 2, is provided with the piston rod 6, which isoperably connected to the cross head 4 and carries within the motor casing 7 the piston P, which is composed of the two members 8 and 9. These members are double diametered members, being provided with the enlarged diametered portions 10 and 11 which are disposed adjacent each other and provide the circumferential recess 12 for the reception of the flexible gaskets 13-13. The adjacent faces of the members 8 and 9 are provided respectively with the sockets l4 and the cylindrical projection 15, for coaction, as shown in Fig. 2, so that the two members 8 and 9 may be forced in interlocked engagement and be held in such engagement by means of the respective locking nuts 16 and 16, which are disposed upon the piston rod 6 and clamp the members 8 and 9 together.

The cylindrical projections of the pistons 8 and 9 of the main piston P are disposed for movement into and out of the respective cushioning chambers 19 and 20 formed in and carried by the caps 21 and 22 respectively of the motor. The cap 22 is provided with the stuffing box 23 through which the piston rod 6 reciprocates, lThe introduction and exhaust ports forthe motor 7 are disposed as at 24 and 25 in the respective caps 21 and 22 and alternate as is the usual custom in admitting the pressure fluid'and 'eiihn astin the same.

"n" "or er to provide a means for properly admitting the pressure fluid to the respective chambers 19 and to assist in propelling the piston P, a channel 26 is provided in each reduced portion 8'- or 9', and; is provided with the inlet 2'2? adjacent the rims ro 11;-ee the piston P. The o positee'nd of the channel; as at 28, is enlarged and has disposed therein the ball valve 29, which is normally seated by means of the sprin'gfll), said spring being held in place y means of the ported ring 31-, which is opened through the; outer endofthe reduced end ofithe piston into the respective chamhers l9 and 20 By this means, it willbe seen that under normal-conditions a certain amount of the pressure fluid at either" side ofitherespective rims 10' and 11-, as for instance when the piston P- is'movihg toward the stufling box port-24; to; the left of the ring 1-0 and. will also enter: the port 27 and will unseat the ball valve 29 IQ-bus the pressure fluid will enterthe chamber 19. to be directed against the end ofthe lug 8 and thusassist inmoving the piston to the right. The, reduced end 9 is then directedrinto the chamloerw 19 andas the ball; valve carried'thereby prevents theescapeof the. pressure fluid trapped therein. through'the hy-pass. or. channel 26,

the desired cushion action is had at the end on the stroke. The ports. 24 and are so end in Fig. 2', will enter the provided, that when a cushioning means at the end of each stroke 5 of the iston P that utilizes the. era fluid of the motor. op tmg What is claimed is:

A reciprocating motor, including a cylinder having two reduced chambers, one at each end thereofi, there being two 0rt's', one in connnunica't'i'on w'ithearcll 'end-o tlie 'Ihain chamber of the cylinder at a'point: adjacent the junction between the maiih chamber and its reducedchamber; a piston havin'ga centrally disposed main chamher engaging portion and two oppositely disposed. cylindrical ends,. said ends 'being'idisposed for snugly fitting into the respective reduced chambers as the piston is reciprocatedg each cylindrical end heingzprovidedr with a my.- ass lead ingfrom its end face to a. point-a jacent to the main cylinder engagin portion, and a spring-closed va1ve. ,infearh yspass fior trap.- ping the pressure fluid, within the, reduced chamben'as the. cylindrical end oi the. piston enters the chamber, thefvmlve opening at the be oi-this s 'oke.to;a.dmit.the. ressu e flu iginto the. c amber at the rearv 0% the cylindrical end ot the? piston to assist in propelling the piston.
